London, Feb 22 (Inditop.com) Actress Sienna Miller is very happy after reuniting with actor Jude Law and is planning to get back into her boyfriend’s house here.

“It’s going really well. I’m so happy actually, he’s great,” mirror.co.uk quoted her as saying with a blush.

The two got engaged on Christmas in 2004 but their relationship soured when Law was caught with the nanny of his children. In July 2005, Law issued a public apology to Miller for having an affair with the nanny.

Despite attempting to salvage their constant on-off relationship, Miller and Law finally separated the following November. However, the pair rekindled their relationship in late 2009 and spent Christmas in Barbados, along with three of Law’s children.

The 28-year-old is planning to move back into Law’s North London pad.

“Jude and Sienna move pretty fast. They are just so into each other. It’s not like they are a new couple. There will be no weirdness, they know each other’s good and bad habits. Even so it’s a house that holds lots of memories,” said a source.

“Jude proposed to her there on Christmas Day in 2004. And they threw such lovely house parties and had such a good time with their extended family,” the source added.
